This is comet C/2013 R1 (Lovejoy). To see this comet you will need some binoculars, or a good DSLR camera with a f2.8 lens. Look to the NW just to the left of the Big Dipper handle. Unless up very high in the hills and away from city light pollution you will not see with the naked eye very well. But it is possible with binoculars and a good camera.
